Louis Leakey and Mary Nicol meet in London.
They marry one year later.Mary Leakey (formerly Mary Nicol) finds a primate skull in Olduvai Gorge,
a gorge 200 miles South of Nairobi, Kenya
that the Leakeys chose as their primary area
of research. Louis and Mary thought that this
skull connected apes and humans, but this was
unfortunately not true.Dating techniques became more accurate
during the 1950s, aiding the Leakeys and
other researchers in their field.Mary Leakey discovers a primate skull that was
dated to be around 1.75 million years old. This
skull captured the attention of National
Geographic and gave the Leakeys funding.Louis Leakey dies of a heart attack.An archaeologist named Donald Johanson finds
parts of a skeleton that date back 3.2 million
years. The importance of this discovery (other
than the skeleton's incredible age) was Lucy's
bone structure, which confirmed that Lucy
walked upright (affirming that humans had been
bipedal before our brains developed).Mary Leakey finds a set of hominid footprints
at a camp at Laetoli, 35 miles from Olduvai.
These footprints increased the evidence that
hominins of the time walked on two feet.Mary Leakey dies in Nairobi, at age 84.
The Leakeys redefined the way we think
about our species' origins, proving that
we began in Africa and finding substantial
evidence to back up this claim, as well as
inspiring many other young men and
women to go into the field of palaeoarchaeology.Louis and Mary Leakey made incredibly
contributions to our theory of the evolution of
the humans species, having collected sizable
evidence that the human race started in Africa
such as finding human skulls from millions of
years ago.
